Glasgow University has begun to ‘decode’ brainwaves. If successful, researchers believe the findings could lead to brain-computer interface. BBC News reports:
Scientists believe they are a step closer to being able to read people’s minds after decoding human brainwaves.
Glasgow University researchers asked volunteers to identify different emotions on images of human faces.
They then measured the volunteers’ resulting brainwaves using a technique called electroencephalography (EEG).
Once researchers compared the answers to the brainwaves recorded, they were able to decode the type of information the brainwaves held relating to vision.
The research was carried out by the university’s institute of neuroscience and psychology.
Six volunteers were presented with images of people’s faces, displaying different emotions such as happiness, fear and surprise.
